Recall N262576260 has just come out. My truck has the same symptoms/conditions consistent with the recall. I have a code P0420, check engine light, high oil consumption and loss of power. also, the GM representative i spoke with told me i have an open recall N242450631. it does not show on the NHTSA website and it does not show at the dealer. the high oil consumption has allowed the turbo to damage the catalytic converter and something in the engine to tap due to less lubrication.
I was driving my truck (2019 GMC Sierra 5.3L) while pulling a travel trailer to go camping. As I was getting onto the interstate, without any prior warning, all at once the truck began to shake, make a concerning noise, and various warning lights began displaying on the driver information panel. I pulled the truck off as safely as possible and had the truck towed to a GM Dealer for service. After investigating the engine, the service department informed me that an exhaust lifter failed, camshaft lobe was damaged, and a cylinder wall was scored resulting in the engine having to be replaced. As…
Engine died while on the freeway. Had the truck sent to my dealer via flatbed with AAA. They diagnosed it as the known lifter issue—lifter broke and metal went into the camshaft and scored it. So I need to replace the camshaft and lifters. They’re quoting me $12k for that. I have 83000 miles on this car and I take very good care of it.
The contact owns a 2019 GMC Sierra 1500. While driving 65 MPH with cruise control activated, the messages "Service ESC", "Service Park Brake", and an unknown message was displayed, causing the cruise control to deactivate. The check engine and transmission warning lights illuminated. The vehicle was jerking and the transmission was lagging while driving. The vehicle was taken to the dealer, who determined that the camshaft and lifter needed to be replaced. The manufacturer was notified of the failure by phone and advised the contact to file a complaint with the NHTSA Hotline. The failure…
Engine failure. My engine is near failure, loud knocking, check engine light and trusted repair shop analyzed. The repair diagnosis is that the engine will fail in the very near future and that is not safe to drive because of risk of failure. I like the truck and it is still in great condition (129k miles). So, I search for recall information and see the 6.2L 2021-2024 recall and see there is additional investigation underway on newer models. Is it possible it goes back to the redesign of the pick-up in 2019? It sounds like the same issue.
Often blows blue smoke and oil out exhaust, and uses more engine oil that would ever be expected, especially when pulling a load. I took it to Rusty Drewing GMC dealership IN Jefferson City, Missouri, and they told me everything was fine, that they could not find a problem.
The vehicle has experienced repeated Electronic Stability Control (ESC) malfunction warnings that appear related to a prior GM recall for ESC malfunction codes. These warnings occurred before and after dealer repairs. The ESC malfunction may have affected other safety systems. I was involved in two separate accidents while driving this vehicle, and in both incidents the airbags did not deploy. In one accident, the vehicle struck multiple objects in a frontal collision at significant speed. The airbags did not deploy at all. I lost consciousness, sustained injuries, and have experienced ongoing…
The contact owns a 2019 GMC Sierra 3500. The contact stated that while attempting to switch lanes, the side-view cameras failed to operate as needed. The vehicle was taken to a dealer where it was diagnosed with a disconnected wire from the side-view cameras. The wire had poor connection, which caused the cameras to fail due to low voltage. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the part to repair the vehicle was no longer manufactured. The failure mileage was 53,004. The VIN was unavailable.
I am getting warning signs on the dashboard saying that my brake booster performance has failed and I need to service the brake booster , the brakes are very hard to press, I need longer stopping distances,and traction control and stability control towing harness my speed has been limited to 43 mph and it's saying that the mass air flow system is has low circuit

The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving approximately 5 MPH, the rear wheels locked up. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the brakes needed to be replaced. The vehicle was repaired; however, the failure recurred intermittently. The vehicle was taken to another local dealer, Walker Bros Chevrolet (700 Erie St, Edinboro, PA 16412); for a second opinion, and the transmission and TCM were replaced. The vehicle was repaired; however, the failure reoccurred. Upon…
The contact owns a 2019 GMC Sierra 1500. The contact stated while driving approximately 20 MPH, the vehicle came to a screeching stop. There were no warning lights illuminated.

Why is my 2019 GMC Sierra burning or losing oil?
23 of the 729 owner complaints NHTSA has on file for the 2019 GMC Sierra (3.2%) describe excessive oil consumption or oil leaks. One owner wrote: "Recall N262576260 has just come out. My truck has the same symptoms/conditions consistent with the recall. I have a code P0420, check engine light, high oil consumption and loss of power." (NHTSA complaint 11772324, October 2026). If it happens to your car, check your VIN for open recalls at nhtsa.gov/recalls and report the problem to NHTSA; complaints are what trigger investigations.
Check your own Sierra
Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports. To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
